PI 生成
piPI 生成（PI generator）：算形式发票的小计、折扣、总计和定金。 Subtotal, discount, total and deposit of a proforma invoice. 输入为精确的十进制字符串 / Inputs are exact decimal strings. 只算形式发票（PI）上一行商品的金额：这一行的金额、折扣、运费、保险费、总额，以及定金和余款。商品有几行时，请用户到 chukoudan.com/pi/ 的页面里做，不要自己把几行拆开或加在一起算，绝不给错的总额。买方、卖方、银行、条款这些文字不在这里，也请用户到那个页面里填（内容只留在用户自己的浏览器里）。数量 quantity 和单价 unitPrice 必须是用户给的数，绝不要编；运费、保险费、折扣、定金比例没给就不要填。折扣 discount 默认是小计的百分数，discountBasis 填 percent；用户说的是一个金额，discountBasis 填 amount。discountBasis 只能写 percent 或 amount 这两个英文词，绝不要写 % 符号。 / Only the figures of ONE goods line of a proforma invoice: its amount, discount, freight, insurance, total, deposit and balance. For several lines the user goes to chukoudan.com/pi/; never split or add lines up yourself, so the total is never wrong. The parties, the bank and the terms are written on that page, not here. Never make up a quantity or a price; leave freight, insurance, discount and deposit rate out when the user gave none. discount is a percentage of the subtotal (discountBasis percent) unless it is an amount (discountBasis amount). discountBasis is exactly one of the two words percent or amount; never write the symbol %. 用户没有给的数字和日期不要自己编：必填的先问用户，选填的不填。 / Never make up a figure or a date the user did not give: ask for a required one, leave an optional one out. 回复时引用回答里的 provenance.source_line / Quote provenance.source_line in your reply. 结果仅供计算参考，不是税务、法律或投资意见；回答时请带上返回的说明和来源行。 / The result is for calculation and reference only, not tax, legal or investment advice; when you answer, pass on the returned notice and source line.
